Description

Technical Field

[0001] The utility model relates to the technical field of cable release hooks, in particular to an automatic resetting cable release hook. Background Art

[0002] The cable release hook is a special equipment installed on the dock for ship cable winding and mooring. It is an alternative to traditional mooring bollards. Compared with mooring bollards, the cable release hook not only reduces the labor intensity of workers and improves the efficiency of cable retraction and release, but also ensures the safety, reliability and durability of the dock. The cable release hook is mainly composed of a cable release mechanism and a cable winding mechanism. It is particularly suitable for large docks. The mooring cable is quickly unhooked and released, thereby ensuring the safety of the dock and the ship and avoiding huge losses. During the use of the current cable release hook, when the ship leaves the port, the steel hook rotates to release the cable, and then the steel hook needs to be reset to prepare for the next hooking. However, when resetting the steel hook, it generally needs to be reset manually, and the manual reset efficiency is low. Therefore, we propose an automatic reset cable release hook to solve the above problem. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention provides an automatic resetting cable release hook, which solves the problems raised in the above background technology.

Two hooks 4 are fixed on the surface of the rotating shaft 3. An elastic lifting component 5 is provided on the top of the base plate 1 to facilitate the hook 4 to release the cable. A guide seat 6 is fixed on the top of the base plate 1. , a limit block 7 adapted to the hook 4 is slidably connected to the guide seat 6, the bottom of the limit block 7 is in contact with the two hooks 4, a hydraulic cylinder 8 is fixed to the top of the guide seat 6, and the ejection end of the hydraulic cylinder 8 is fixedly connected to one side wall of the limit block 7, a driving mechanism 9 for automatically resetting the two hooks 4 is provided on the top of the bottom plate 1, a winding seat 10 is fixed to the top of the bottom plate 1, and the top of the winding seat 10 is rotatably connected to the cable winding disc 11 through a bearing, and an annular groove 1 is provided on the top of the winding seat 10 Finally, the hydraulic cylinder 18 is started again to push the limit block 7 to move and reset the reset hook 4, and the automatic reset of the hook 4 can be completed.

[0020] like Figure 2 and Figure 4 As shown, in some embodiments, the elastic lifting assembly 5 includes a limit seat 501 fixed on the top of the base plate 1, and a lifting plate 502 is slidably connected inside the limit seat 501. The top of the lifting plate 502 fits against the bottom of the two hooks 4, and four springs 503 are fixed to the bottom of the lifting plate 502. The bottom ends of the springs 503 are fixed to the limit seat 501. When in use, the hook 4 will squeeze the lifting plate 502 after it is reset, and the lifting plate 502 will squeeze the spring 503 after it moves. When the hook 4 is no longer restricted by the extrusion, the lifting plate 502 can be driven to reset under the reset force of the spring 503. After the jacking plate 502 is reset, the hook 4 can be lifted, rotated and cabled.

[0021] like Figure 1 、 Figure 2 and Figure 3As shown, in some embodiments, the driving mechanism 9 includes two mounting seats 901 fixed on the top of the base plate 1, and a guide rail 902 is fixed on the top of the mounting seat 901.
